ESP

® Warning Lamp Comes ON Steady

S5JB0E4604009

Wiring Diagram
Refer to “ESP

® Warning Lamp Does Not Come ON at Ignition Switch ON”.

Circuit Description
Operation (ON/OFF) of ESP

® warning lamp is controlled by ESP® control module through lamp driver module in

combination meter.
If ESP

® system is in good condition, ESP® control module turns ESP® warning lamp ON at the ignition switch ON,

keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ESP

® warning lamp is

turned ON continuously by ESP

® control module. Also, it is turned ON continuously by lamp driver module when the

connector of ESP

® control module is disconnected.

Troubleshooting

Inspection

6

1) Check CAN communication circuit between combination

meter and ESP

® control module referring to “DTC

U1073: Control Module Communication Bus Off”.

Is CAN communication circuit in good condition?

Substitute a known-
good combination meter
and recheck. If ABS
warning lamp remains
ON, substitute a known-
good ESP

® hydraulic

unit / control module
assembly and recheck.
